Possibility Storm: Rivals of Ixalan #7
Hello Puzzlers! This week we have the single hardest puzzle we have ever put out to the public! There are dozens of people who compete in the weekly time trials, often competitive answers are separated by seconds, and the top 20+ answers are right 90% of the time. This puzzle not only had answers in the 24 hour block but we received less then 5 correct answers overall! So why is this so difficult? Once you go through the answer it will seem quite simple. So why is it so hard? Opponents choice. In the past you may have seen puzzles with walking ballista, and the number of options available there were often quite high. In this case the number of attacking creatures and interactions and windows to target them makes the paths staggering. Also the interaction between spires and skinshifter needs a moment of time to process or you could end up with bad math. Good luck, you are going to need it.
These puzzles are free to play, but if you like to challenge yourself or others, then you can get early access over here. Each puzzle has a unique solution, but if you find a better one that our crack staff of puzzle analysts missed, you can reach us here or on Twitter @mtgpuzzles.
